Every year Marvel likes to do something big at Comic-Con to get audiences excited for what's coming next. Though we won't see the film until 2015, Marvel brought out Joss Whedon to announce the title of 'The Avengers 2.' It's 'The Avengers: Age of Ultron.'

What this means is that the story is likely to follow that recently published comic book series. The story begins with New York in ruins because of Ultron, and that's a surprise because you would suspect they'd use Thanos (Thanos is likely involved in some way or another, but we're just going by a title). According to Wikipedia, Marvel comic book editor Tom Breevort saw this as a possibility, as he had said earlier:

My guess is, probably sooner or later if they do enough Avengers films, they'll get to Ultron ... We didn't do Age of Ultron specifically for that. However, since we're so integrated at Marvel, I wouldn't be surprised if they got to that point at some point, to see some elements that may have happened during Age of Ultron or any of the previous Ultron stories, make it into a film. But that's just conjecture on my part.

This is the first of many details to emerge from this project, but there's no denying it's exciting. 'The Avengers: Age of Ultron' will hit theaters May 1, 2015.
